jQuery.fn.swap = function(b) {
  b = jQuery(b)[0];
  var a = this[0],
    a2 = a.cloneNode(true),
    b2 = b.cloneNode(true),
    stack = this;

  a.parentNode.replaceChild(b2, a);
  b.parentNode.replaceChild(a2, b);

  stack[0] = a2;
  return this.pushStack(stack);
};

function changeVideos() {
  $('.wrap-grid > div:nth-child(n + 2)').click(function() {
    $('.wrap-grid > div:nth-child(1)').swap($(this));
    $(this).off();
    changeVideos();
  })
};
changeVideos();

我试图将右侧的三个元素之一与左侧的元素交换。与示例相同，我尝试与 jquery 交换，但这是重新加载 dom 元素并且它们正在闪烁。有没有办法通过操纵布局order中flexbox的属性来做到这一点。grid

Answer 1

order您可以使用纯 JavaScript访问和设置他们的 flexbox ：

document.getElementById('your-id').style.order = 2
document.getElementById('your-id').style.order // returns "2"

或 jQuery：

$('#your-id').css('style', 2)
$('#your-id').css('style') // returns "2"
